3 Generations Birthday Party - Help!!

My daughter (soon to be 3) and I (soon to be 30) are traveling from Georgia to Wisconsin for a visit to my Mom (and the rest of the family) and while we're there we'll be having a birthday party for the three of us. I'd like to do a cake that can somehow be for all of us. I'm traveling 1100 miles, so I won't have any of my supplies and I can't premake too much. Thanks to anyone with any cute ideas!

I guess one thing we all have in common is that we all like the beach. My daughter and I like Strawberry Shortcake (that was her party's theme last year). Mom likes anything to do with the beach, lighthouses, sand, seafood. My daughter is simply an angel, she's the sweetest little thing and is so much fun, makes us laugh no matter what we're doing. We all have a soft spot in our hearts for animals, especially cats...we have four between us. Wow, it's hard to describe us when put on the spot!!! Hope you all can help...I'm desperate!!! Thanks.

How about strawberry shortcake at the beach with her cat??!!! You could have St. Shortcake sitting in a lounge chair with a bikini on wearing sunglasses...cat beside her with sunglasses on...on a beach themed cake!

Done right, it would probably be a pretty cute cake...and definitely unique! lol Just trying to help.......
